title: STMicroelectronics STM32 Chrom-Art Accelerator DMA2D
description:
Chrom-ART Accelerator(DMA2D), graphical hardware accelerator
enabling enhanced graphical user interface with minimum CPU load
It can perform the following operations.
- Filling a part or the whole of a destination image with a specific color.
- Copying a part or the whole of a source image into a part or the whole of
a destination image.
- Copying a part or the whole of a source image into a part or the whole of
a destination image with a pixel format conversion.
- Blending a part and/or two complete source images with different pixel
format and copy the result into a part or the whole of a destination image
with a different color format. (TODO)
